ID Dummy 3.4.24

Our first information about a hand comes from the auction. The second comes from partner’s lead. The third from dummy. In addition, we will learn from partner’s signals and from the choices that our opponents and partner make. On this hand, looking at the auction and dummy, what do you think declarer’s plan will be? At the end of trick four, we should have a very good picture of the hand and know exactly what declarer is planning on doing. How can we counter that plan?
